Aluminum derivatives of N-oxypyridyl thiol and process for their preparation

ABSTRACT

An antiperspirant-deodorant composition containing in a cosmetic carrier an active compound of the formula  WHEREIN X is chlorine, bromine and R1SO3 wherein R1 is alkyl of 1-4 carbon atoms, phenyl, chlorophenyl, hydroxyphenyl and 2-oxo 10-bornanyl and R is hydrogen, chlorine, methyl or methoxy.

The present invention relates to a deodorant-antiperspirant cosmetic composition, to certain compounds usefully employed in these compositions and to a process for preparing these compounds.

It is well known that perspiration which results from the secretion of sudoriferous glands causes, on the one hand, moistness of the skin and, on the other, the appearance of body odors due to a decomposition of the perspiration by microorganisms.

To combat moistness of the skin it has heretofore been proposed to reduce perspiration by the application to the skin of conventional antiperspirant compound-containing compositions. These active compounds include, for instance, aluminum salts such as aluminum chlorhydroxide complex, known under the tradename CHLORHYDROL, sodium aluminum chlorhydroxy lactate complex, known under the tradename CHLORACEL, aluminum phenylsulfonate, aluminum chlorhydroxy allantoinate, aluminum dihydroxy allantoinate, aluminum isopropylate, and various other organic aluminum compounds, such as, for example, the complex combination of aluminum chlorhydroxide with propylene glycol known under the tradename REHYDROL.

While compositions including these conventionally known antiperspirant compounds may reduce perspiration, they do not at the same time effectively eliminate body odor which results from the decomposition of perspiration by microorganisms. Accordingly, in such compositions it was found necessary, in order to combat effectively the formation of body odor, to add a separate deodorant compound or agent which most often was an active agent against microorganisms. Thus, there resulted a composition containing an antiperspirant component or agent and an antimicrobe compound or agent, the latter generally being hexachlorophene.

However, such compositions, which are now widely used, still have certain drawbacks. For instance, it has been found that, in certain cases, the antiperspirant component or agent which can contain certain impurities as trace materials, actually inactivates to a significant degree, the antimicrobial action of the deodorant component or agent, thereby inhibiting to a significant degree the fulfilment of the double duty of the composition, i.e. its role as a perspiration inhibitor and as a deodorizer.

Further, it has also been found that the joint use of two active components which quite often are of very different nature and exhibit quite different physicochemical characteristics, poses very delicate and difficult problems on the formulation level. As will be appreciated, it is important, first of all, that there be no incompatibility, i.e. no interaction, between the two active components and secondly that there be no incompatability between either or both of these two components and the other components of the ultimate formulation.

Thus, it can easily be seen that the preparation of an acceptable formulation using two separate components, one of its antiperspirant activity, the other for its deodorizing effect, can present problems that are difficult, at best, for the formulator to overcome, especially if these active components exhibit substantially differing solubility characteristics for a given solvent. Ideally, then it would be desirable to use but a single component exhibiting multiple activity, i.e. one which would exhibit both acceptable perspiration inhibiting characteristics and deodorizing activity. Until now the art has not provided such a component. However, the applicants have found in a completely surprising way that certain aluminum compounds exhibit both effective perspiration inhibiting activity and effective deodorizing characteristics and the use of these aluminum compounds thus solves the problem of deodorant-antiperspirant compositions in the sense that, according to the invention, it is no longer necessary to add a separate anti-microbe or deodorant component to a composition containing a conventional antiperspirant aluminum compound to prevent not only the formation of body odors, but simultaneously to inhibit perspiration.

The compositions according to the present invention which bring about an undeniable technical advance, have been proven to exhibit both perspiration inhibiting activity at least equal and in many cases superior to conventionally known antiperspirant compositions and at the same time a powerful antimicrobe activity, while employing but one component to achieve both these desiderata.

Thus, one object of the present invention is to provide a deodorant-antiperspirant composition comprising in a suitable cosmetic vehicle as an active component a compound of the formula ##SPC2##

When the compositions according to the invention are in the form of a lotion for topical application to the skin or scalp, the concentration of active component is preferably between 0.01 and 0.1 weight percent.

These lotions comprise a solution of said active component in a solvent selected from the group consisting of water and an aqueous solution of a lower alkanol, such as ethanol or isopropanol, said aqueous solution of the lower alkanol generally containing from 30 to 90% by weight of said lower alkanol.

If desired, these lotions can also contain a conventional film forming cosmetic resin and thus provide a hair-setting lotion. Generally, the resin is one which has a molecular weight ranging from about 10,000 to 3,000,000 and is present in amounts of about 0.5 to 5% by weight.

Representative cosmetic resins that can be used include polyvinylpyrrolidone having a molecular weight between 10,000 and 70,000, polyvinylpyrrolidone/vinyl acetate copolymers (70-30%/30-70%), copolymers of vinyl acetate and an unsaturated carboxylic acid such as crotonic acid (molecular weight -20,000); copolymers resulting from polymerization of vinyl acetate (75-85%), crotonic acid (5-15%) and an acrylic or methacrylic ester (5-15%) or an alkyl vinyl ether (5-15%); copolymers resulting from the copolymerization of vinyl acetate (63-88%), crotonic acid (5-15%) and (a) (5-25%) of a vinyl ester of an acid with a long carbon chain having 10-22 carbon atoms or (b) of an allyl or methallyl ester of an acid with a long carbon chain having 10-22 carbon atoms; copolymers resulting from the copolymerization of 65-80% of an ester of an unsaturated alcohol having 2-12 carbon atoms and a saturated short carbon chain carboxylic acid having 2-5 carbon atoms, 7-12% of an unsaturated acid having 4-20 carbon atoms and 10- 20 % of at least an ester of a saturated alcohol having from 8-18 carbon atoms and an unsaturated acid having from 4-20 carbon atoms, and the copolymers resulting from the polymerization of at least an unsaturated ester and at least an unsaturated acid.

When the composition according to the present invention is in the form of a cream, the concentration of active component, in the cream base or carrier is preferably between 0.01 and 5 weight percent. The cream base or carrier is generally an oil-in-water emulsion comprising about 10-50 weight percent oil and 90-50 weight percent water.

Representative oils that can comprise the oil phase of the emulsion include:

(a) a hydrocarbon oil such as paraffin oil, purcellin oil, perhydrosqualene, and a solution of microcrystalline wax in an oil;

(b) animal or vegetable oil such as sweet almond oil, avocado oil, calophyllum oil, lanolin, castor oil, horse oil, pork oil and olive oil;

(c) mineral oil having an initial distillation point, at atmospheric pressure, of about 250°C and a final distillation point of about 410°C; and

(d) saturated ester such as isopropyl palmitate, alkyl myristates wherein the alkyl moiety is selected from isopropyl, butyl and cetyl, hexadecyl stearate, ethyl palmitate, triglyceride of octanoic and decanoic acid, and cetyl ricinoleate.

In the oil phase it is also possible to use silicone oils soluble in other oils, such as dimethylpolysiloxane, methyl-phenylpolysiloxane, and the silicon-glycol copolymer.

To promote the retention of oils, the oil phase can also contain waxes such as carnauba wax, candellila wax, beeswax, microcrystalline wax and ozokerite, the amount of wax employed generally ranging from about 0 to 20 percent by weight based on the weight of the oil employed in said oil phase.

Fatty alcohols such as stearyl alcohol, cetyl alcohol, 2-octyl 1-dodecanol, oxyethylenated fatty alcohols, propyleneglycol and the like, can also be used in making the creams according to the invention, said fatty alcohols usually being present in amounts of about 0.5 to 10 percent by weight of said composition.

When the compositions according to the invention are in the form of sticks, the concentration of active compound is preferably between 0.01 and 5 weight percent of said composition.

The antiperspirant-deodorant made in stick form in accordance with the present invention can be produced from a molten wax in which is incorporated the active compound of this invention. Generally, the active compound is incorporated into the stick as an emulsion of a solution thereof in water, in lower alkanol or in an aqueous solution of a lower alkanol, as defined above.

It has also been found advantageous, in the preparation of these antiperspirant-deodorant sticks to introduce into the wax component about 0.5 to 10 weight percent based on the weight of the wax, an oil or fatty alcohol, also as defined above.

The emulsifier employed to produce the antiperspirant-deodorant stick of this invention can be any conventional emulsifier generally used in cosmetic formulations of this type. In particular, it has been found that such emulsifiers as fatty amides, including diethanolamide and the like are usefully employed.

In the antiperspirant-deodorant sticks of the present invention, the aqueous, alcohol or dilute alcohol suspension or solution of the active component of the present invention represents about 0.5 to 20 percent by weight of the said stick.

When the composition according to the present invention is in powder form, the concentration of active component as defined above is preferably between 0.01 and 5 weight percent of the total weight of the composition.

These compositions in powder form contain, in addition to the said active component, a conventional powder base and a binder. The powder base can be any conventional essentially non-hygroscopic powder commonly used in cosmetic or pharmaceutical products. Illustrative of such materials are talc, starches such as rice starch or cornstarch, clay such as kaolin or bentonite, powdered stearates such as lithium stearate, zinc stearate and magnesium stearate; and mixtures of the same. Typical binders include, mineral oil, vegetable oil, lanolin, petroleum, fatty alcohols, isopropyl esters such as isopropyl myristate and isopropyl palmitate and the like.

Preferably, the cosmetic composition of the present invention is in the form of a sprayable aerosol which can be an alcohol-based spray or a dry or powder spray.

In this particular embodiment, the concentration of active component is generally between 0.01 and 5 weight percent of the total weight of the aerosol composition.

Alcohol-based spray in aerosol form contains, in addition to the active component of this invention, (a) an anhydrous alcohol selected from the group consisting of ethanol and isopropanol and (b) a liquified aerosol propellant under pressure such as a halogenated hydrocarbon including, for example, trichlorofluoromethane or dichlorodifluoromethane and their mixtures. Obviously, other conventional aerosol propellants, inert with respect to the active component of this invention can also be employed.

In the case of a dry or powder spray, the composition contains in addition to the active component of this invention and liquified propellant as defined above under pressure, a powder base and binder as defined above, the powder base being present in amounts of about 0.1 to 15 weight percent of the total aerosol composition and the binder, when present being included in amounts of about 0.05 to 5 percent by weight of said composition. Generally, the propellant is present in amounts of about 66 to 75 weight percent of the total aerosol composition, which is, of course, packaged under pressure.

It is understood that whatever particular form of the present invention is chosen, i.e. a cream, a stick, a lotion or an aerosol spray, any other component generally used in these types of cosmetic compositions which is inert with respect to the active component of this invention can be employed. For instance, it has been found advantageous to include in the composition of the present invention a preservative such as methyl parahydroxybenzoate or propyl parahydroxybenzoate, as well as a perfume.

It has been found that the active component of the present invention, in addition to exhibiting highly desirable antiperspirant characteristics, also exhibits excellent anti-microbial activity, particularly against the following microorganisms: Micrococcus aureus, Bacillus subtilis, Sarcina lutea, Escherichia coli, Aspergillus niger, Penicillium notatum, Mucor mucedo, Saccharomyses cerevisiae, Pityrosporum ovale, and Candida albicans.

Because of these particular properties, the composition of the present invention can effectively be used as cicatrizing, anti-dandruff compositions and for foot care and feminine hygiene. Additionally, the active compound of the present invention can be used as a disinfectant and as a preserving or antiseptic agent.

The present invention also relates to a compound of the formula: ##SPC3##

wherein X represents a member selected from the group consisting of isopropoxy, chlorine, bromine and R₁ SO₃ wherein R₁ represents a member selected from the group consisting of alkyl having from 1 to 4 carbon atoms, phenyl, p-chlorophenyl, p-hydroxyphenyl and 2-oxo 10-bornanyl, and R represents a member selected from the group consisting of hydrogen, chlorine, methyl and methoxy.

bis-(2-N-oxypyridyl thio) aluminum chloride,

bis-(2-N-oxypyridyl thio) aluminum bromide,

bis-(6-methyl 2-N-oxypyridyl thio) aluminum chloride.

The present invention is also related to a process for preparing these compounds, which process can be represented by the following scheme. ##SPC4##

As can be seen from the reaction scheme represented above, the process comprises initially reacting aluminum isopropylate with an N-oxide of 2-pyridine thiol, (formula II) to produce a bis-(2-N oxypyridyl thio) isopropoxy aluminum (formula III) as an intermediate. Generally, the mole ratio of N-oxide of 2-pyridine thiol to aluminum isopropylate is 2:1 and the reaction is usually carried out in an anhydrous solvent such as an alcohol, and more particularly methyl, ethyl, isopropyl and tertio-butyl alcohol, an aromatic hydrocarbon such as benzene and toluene, or a chlorinated hydrocarbon such as chloroform and dichlorethane. Obviously other conventional anhydrous solvents, inert to the desired reaction, can also be used. The reaction can be carried out at ambient temperature or even at temperatures as high as about 50°C.

The resulting reaction product can, if desired, be isolated, and if isolated, the said reaction product is then suspended or dissolved in an anhydrous solvent, as defined above, prior to further reaction to produce the compound of the present invention. However, generally, the product of the reaction of aluminum isopropylate and an N-oxide of 2-pyridine thiol is not isolated and there is introduced into the reaction mixture containing this reaction product, represented by formula III, in an anhydrous solvent, an acid selected from the group consisting of hydrochloric acid, hydrobromic acid or sulfonic acid, said acid being employed in essentially stoichiometric proportions. When hydrochloric or hydrobromic acid is employed it can be introduced in the dry gaseous form or it can be introduced as a solution in an anhydrous solvent, as described above. When a sulfonic acid is employed it can be introduced in pure form or, again, as a solution in said anhydrous solvent. Generally, this step of the reaction is carried out at ambient temperature and at atmospheric pressure. In some cases the reaction is exothermic but it is not necessary to cool it.

There will now be given by way of illustration and without any limiting character several examples of preparation of the active compound of the present invention and some representative examples of the preparation of the deodorant-antiperspirant composition of the present invention employing these compounds.
